摘　　要：提出一种云计算环境下得到能效输出的最大值的必要条件;从简化能效计算步骤提高计算效率出发,对计算机功率和CPU工作频率状态间关系的数学表达进行了改进,通过CPU高发率和频率来计算云环境下能效,达到简化能效测量步骤的目的,从而能够对云系统的能效进行高效准确的评估,并为云环境下的多CPU能效测量和优化工作奠定扎实的基础。This paper proposes an essential condition for producing a maximal energy efficiency output under a cloud computing environment. Energy efficiency computing procedures are simplified to increase computing efficiency, and improvement is made to the mathematical expressions of the relationship between computer power and the CPU operating frequency. The energy efficiency is computed under cloud environment by using the high CPU usage and frequency. In this way, energy efficiency of the cloud system can be evaluated in an efficient and accurate manner, thereby laying a solid foundation for multi-CPU energy efficiency measurement and optimization under cloud environment.
